Yahoo's image and video hosting website Flickr has released a major update to its iOS app, adding a number of features that will allow it to compete with the likes of Facebook's Instagram and Google's Snapseed. The update, which is live in the App Store now, introduces a "completely new photo taking experience" with live filters and editing.Live Filters let you see how your photo looks while you take it. Swiping through live filters, you can choose composition grids, focus lock and exposure points to better set up your shot. Even our preview tiles let you see what your shot looks like live. All of our filters are also customizable after you’ve taken the photo. Y
